Title: Topological systems for quantum technologies

Speaker:Dr. Abhijeet Alase, University of Sydney

Abstract: Emerging quantum technologies, including quantum computation, communication, sensing, and simulation, rely on engineering highly unnatural quantum states. In this talk, I will examine the pivotal role of topological quantum systems in providing robust physical platforms for realizing these technologies. I will begin with an overview of topological systems and their protected features. Then, I will discuss the theoretical problems relevant to the advancement of topological platforms for quantum technologies. With an eye toward the development of Majorana-based topological quantum computers and topological quantum sensors, I will talk about new approaches to examining the stability of topological edge states. Additionally, I will discuss how the performance of Majorana-based quantum computers can be boosted by incorporating a new class of local measurements. I will conclude by highlighting promising avenues for the advancement of quantum technologies, including devices based on superconductor-semiconductor hybrid topological systems.
